Why is an Automated Top-Off so important?
One of the most important aspects of an aquarium system is the stability of its water chemistry parameters. Fluctuations in pH, temp, salinity, etc., can reek havoc on any saltwater – or freshwater for that matter – aquarium. Auto top-off kits are worth their weight in gold because they do 24/7 what you and I would be unable to do unless you had all the time in the world to constantly add water to your aquarium minute by minute. Allowing an automated system to replace the perpetual evaporation of a working aquarium can keep your water parameters from ever changing. In fact, you have the ability to create water stability by using buffering agents in your top-off water to guard against diurnal (24hr cycle) pH swings, or using Kalkwasser solutions to maintain calcium levels, the possibilities are endless. Last but not least, your aquarium or refugium will have a much better chance of keeping a constant water level since it won’t rely on your memory to add water before the pumps start sucking air. If your memory is anything like mine there is the tendency to let it slip your mind that the aquarium needs attention. An automated top-off also provides some freedom if you are going to be out of town for a few days.
All in all, when using and automated top-off, the peace of mind you gain knowing that your aquarium will have constant environmental stability is priceless when using an automated top-off system.
